2 SHEETS-SHEET 1 Filed Aug. 12, 1949 INVENTOB ATTORNEYS IIIIIII'III/July 1, 1952 H. L. CANUP COMPENSATING BEARING FOR CLOTH ROLLS OF LOOMS 2SHEETS-SHEET 2 Filed Aug. 12, 1949 flL. Carl/zap INVENTOR ATTORNEYSPatented July 1, 1952 ooMPE sA'riNG Ems-memen os Application AugustlThis invention relates to looms, the primary object of the inventionbeing to provide means for insuring the accurate and even winding of thecloth on the cloth roll of a loom which operates in conjunction with aloom take-up roll.

An important object of the invention is to provide vertically adjustablebearings in which the shaft of the cloth roll of a loom, operates, thebearings operating to permit of automatic adjustment of the cloth roll,to compensate for the increased diameter of the roll as the cloth isbeing wound thereon.

Another object of the invention is to provide a device of this characterwhich will reduce the upkeep of the device to a minimum, and willcontribute to the ease of operation on the part of the operator whoremoves the cloth from the roll.

A further object of the invention is to provide a pneumatic compensatingbearing for the cloth rolls of looms, which may be readily and easilyinstalled in loom construction, without the necessity of makingalterations in the loom, in order to install the device.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

ig. 6 is a sectional view taken on line 6-5 of F1 5.

gig. 7 is an elevational view of one of the cylinders of the attachment.

Fig. 8 is a, diagrammatic view illustrating the hydraulic systemcontrolling the movements of the bearings.

Referring to the drawings in detail, the frame of a loom is indicatedgenerally by the reference character 5 and includes the upper breastbeam 6 and lower front girt I.

The usual take-up roll of the loom is indicated by the referencecharacter 8, and the function of this roll is to cooperate with thecloth roll in maintaining the cloth straight or even, while it is beingrolled on the cloth roll.

The cloth roll which is of the conventional structure, is indicated bythe reference character 9 and is mounted on the shaft {0. the ends ofwhich are mounted in the bearings II that are movable in theverticalguides 12.

The bearings are supported on the upper ends of the rods l3 and aredisposed at each end of the cloth roll 9, as clearly shown by Fig. l ofthe drawings.

These rods [3 carry pistons M on the lower ends thereof, which pistonsoperate in the cylinders 15 that in turn are supported on the bracketsl6 secured to the front girt T.

The reference character I! indicates a pipe line which has its endsextending into the lower ends of the cylinders 15, as shown by Fig. 1 ofthe drawings, there being provided a feed pipe 18 connected with thepipe line 11, through the valve 19. The pipe 18 connects with a suitablesource of fluid or compressed air supply not shown. A relief valveindicated by the reference character 20 is of conventional structure,and is mounted in the pipe line to relieve excessive pressure in thepipe line to insure the true operation of the compensating bearings.

It might be,further stated, that the bearings II are secured to thebreast beam 6 by means of the brackets 2| that are bolted to the breastbeam, by means of bolts 22.

From the foregoing it will be seen that by admitting fluid or airthrough the pipe line H, the rods l3 together with their bearings whichare supported by the rods, will move upwardly, and since the shaft ofthe cloth roll is mounted in the bearings, the cloth roll will be movedinto contact with the take-up roll of the loom. As the cloth is wound onthe cloth roll 9 and the diameter of the cloth roll increases, thebearings II will move downwardly compensating for the increased diameterof the cloth roll, insuring an even pressure between the cloth roll andtakeup roll to provide for the even winding of the cloth on the clothroll.

Should the cloth roll be moved downwardly to a degree to compress airwithin the cylinders l5, beyond a predetermined pressure, the reliefvalve 20 will operate to relieve excessive pressure and prevent bindingbetween the take-up roll and cloth roll of the loom.

While I have shown and described the device as used in conjunction witha compressed air Having thus described the invention, what is 5 claimedis:

An adjustable cloth roll bearing adapted to be attached to a loom frame,in which a take up r011 operates, comprising vertical guides,

bearing members mounted for vertical movement 10 longitudinally withinthe vertical guides and in which the ends of the shaft of such clothroll are mounted, cylinders mounted within the loom frame, pistonsincluding piston rods, operating within the cylinders, said bearingmembers being 7 connected to the upper ends of the piston rods, a pipeline common to both cylinders through which air under pressure is passedinto the cylfile of this patent:

termined pressure against the take-up roll, controlling the winding ofmaterial on said cloth roll. 1
